UPDATED - Yes, I forgot about the epidural thing. Call the doctor!
ORIGINAL -
Call your OB nurse after hour line. I woudl be worried about your blood pressure being too high or something.
If it is truly just a headache, you might want your OB to see if your hormones are out of control.
If it is just a headache, and there is no underlying cause, then try Excedrin Migrane. Only thing that touches some of my headaches.
Please call your doctor. It is too soon after birth to mess around.
Congrats on your baby!!
